How to Make a Ball Mill: 12 Steps (with Pictures) - wikiHow
For a cylinder drum of the size used above, about 40-60 balls should be sufficient. Larger drums will require more balls. A good rule of thumb is to fill the container about 1/3 of the way with the balls. 2 Add the chemical you need to grind. You can fill the container with as much of the substance to be ground as you'd like.

Planetary Ball Mill PM 100 - RETSCH - highest fineness
Planetary Ball Mill PM 100 Wet and nano-scale grinding with the PM 100 Wet grinding is used to obtain particle sizes below 5 µm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.

Charge behaviour and power consumption in ball mills: sensitivity to ...
The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.
